GraphQL is not dynamic. You can either define multiple queries or add a custom scalar that will have a type like any.

It is somewhat a shame, but it will only allow you static types with no conditions. The only dynamic part is that you can decide what you want to download and what not. Trust me, I looked for it too.

If you're using type-graphql, you could use FieldResolver for something like that, e.g.

UserType.ts

...
@Field(() => String)
firstName: string

@Field(() => String)
lastName: string

UserResolver.ts

...
@FieldResolver(() => String)
public fullName(@Root() userType: UserType): string {
    return `${userType.firstName} ${userType.lastName}`
}

This will create dynamic field fullName based on firstName and lastName, so you can use this analogy to create your own logic.
